The Lundersnooch is a monster of some unknown sort that slipped through a magical door into Krymec's Vault from a remote island swamp location. It then migrated through the Goldvale area to the Zerk Swamp where it took up residence. There are only rumors of it so far, and it is known that it must be quite large since parts of the Zerk Swamp were seen being torn up or disturbed by a likely large beast. However this also brings in to question how a large beast got through a normal door sized portal at the vault. Could it be a shape shifter? Or something like a giant snake that can squeeze through tighter gaps?
